  • Patent number: 8974088
    Abstract: A light-emitting apparatus which is capable of, even when an environmental temperature changes, stably reducing collision noise, vibration noise, and so on generated when the light-emitting apparatus moves from a retracted position to a light-emitting position. A movable portion has a first stopper portion coming into abutment with a first elastic member when the movable portion moves from the retracted position to the light-emitting position, and a second stopper portion coming into abutment with a second elastic member with a higher elastic coefficient than the first elastic member when the movable portion moves from the retracted position to the light-emitting position.

    Abstract: The invention is an apparatus that facilitates the efficient arrangement of a Christmas light display and the efficient removal of that display. The invention accomplishes this through the use of a sliding rod and a multitude of alternating hanger members. The rod and hangers are slidingly attached to each other allowing the positioning of light strands around a columnar article in a knitting arrangement. Accordingly, when removal of the display is desired, an end restraint is removed and the rod is pulled out of the display by sliding through the hangers. The result, therefore, is that the hangers and their attached light strands fall freely from the columnar article.

  • Patent number: 7264391
    Abstract: A lamp fixation system for fixing an electric lamp in a reflector housing in an efficient and effective way. The lamp is positioned in a predetermined position to ensure a reliable electrical power supply. The predetermined position is effected via a cap of the electric lamp which is clamped in a hole in the reflector housing. The cap is provided with spring means for pushing against a surface at the inner wall of the hole in the reflector housing. The spring means comprises a first electrical contact for abutting against an electrical contact in the surface to ensure reliable electric power.

  • Patent number: 6942354
    Abstract: A lighting system is provided including an illumination member, a housing and a resilient element. The illumination member has an electricity conductive portion and a light-emitting portion. The housing defines a chamber for receiving therein the illumination member and includes a socket portion adapted for engaging the electricity conductive portion of the illumination member. The resilient element establishes a contact between the illumination member and the housing for biasing the electricity conductive portion against the socket portion. In a variant, the housing has a light receiving portion defining the chamber and a passageway to the chamber. The housing includes a cap adapted to be removably connected to the light receiving portion for sealing the passageway. In this variant, the illumination member includes a handle portion enabling the removal of the illumination member from the chamber through the passageway.

  • Patent number: 6926433
    Abstract: An automotive headlamp shield may be formed with a self-locating mount. The housing contains a mounting receptacle with three closed sides, an open side, a substantially solid bottom with a laterally extending slot and a top containing an opening. One sub-assembly has a planar surface with an aperture, a solid rear wall and a depending side wall. When assembled, the depending sidewall fits into the slot and protrudes therefrom. Another sub-assembly has an upper surface and four walls including a front wall, a back wall and two sides. A compressible planar latch is associated with the upper surface and a first spring is associated with a side and a second spring is associated with the back. The second sub-assembly is hollow and the springs and the compressible latch are formed from the upper surface and respective sides. The structure is light weight and easy to manipulate.

  • Patent number: 6805463
    Abstract: A shunt element contacting structure for decorative lamp holder mainly includes two contacting plates correspondingly fixed to an inner wall surface of a decorative lamp holder and each having an inward projected elastic portion, and a holding member radially inward extended from the inner wall surface of the lamp holder to hold a shunt element thereto. When a decorative lamp is inserted into the lamp holder with two leads in contact with the two contacting plates, the two elastic portions are also radially outward pushed by a lower portion of the decorative lamp to disengage from two ends of the shunt element on the holding member. And, when the decorative lamp is removed from the lamp holder, the elastic portions of the contacting plates resume to their radially inward projected positions to contact with two ends of the shunt element to thereby provide a shunt path.

  • Patent number: 6793380
    Abstract: A joint (52) for connecting arm portions (40, 42) of a ceiling or wall mounted support system includes housing members (60,62) with an annular bearing (64) interposed between opposed surfaces (82,84) thereof. The housing members are clamped together on an axle (98) such that a braking force generated between the bearing and the housing member surfaces opposes rotation of one arm portion relative to the other. A variable braking force is generated between the bearing and surfaces (206) of the housing members which are generally perpendicular to the opposed surfaces (82,84). The variable braking force is generated by a spring (182) and is greatest when the arm supporting a piece of equipment (24, 26, 28, 56) is at its lowest point, relative to the horizontal. This overcomes the increased forces in the spring which otherwise tend to cause the arm portion (42) to drift upward.
